Within a few hours the track mounted crushing plant R900 can be changed from an impact crusher to a jaw crusher (R800) - and vice versa.
Therefore the plant can be optimized to the different requirements of the feeding material and guarantees a versatile operation.
Both crusher units (R80 and R90) are installed fully hydraulically and based on the same basic chassis. The hydrostatic drive system allows a clockwise or anti-clockwise operation of the crusher. So it is possible to install both crushing units on the same basic frame.
Ease of transport and high performance were key factors to purchase Rockster R900 impactor
The number of demolition projects has been increasing steadily over the years, and the disposal of construction waste has become more and more expensive. The next logical step for Martin Meier Erdbau from Velburg, in the Upper Palatinate area of Germany, was the purchase of a mobile crusher so that the demolition material could be recycled anywhere and at any time. It was an easy and quick decision for the entrepreneur: The Rockster impact crusher R900.
From demolished concrete to recycled and reusable aggregate
Demolition of concrete structures contains a large portion of high-quality building materials that can be recycled. To return these resources, the demolition is first processed in recycling plants such as mobile crushers, so that it can then be returned to the building material cycle as recycled aggregate. Dr. Sonnenberg from the magazine "Beton" explains in an interesting and descriptive report how concrete is processed, what's important to take care of and how it can then be used again as a building material.
Reliability. After 11 years of quality crushing with R900, it’s time for a larger Rockster impactor.
Reliability pays off. The Slovenian construction company AGM Nemec has been a satisfied Rockster R900 customer for almost a decade and, thanks to up-and-coming business, has now invested in the next impactor - the track-mounted mobile impact crusher R1100S.
